ATTORN EY Patented May 28, 1935 MANIFOLD FOR TUBULAR DRIERS Adolph W. Lissauer, Louisville, Ky., assignor to Louisville Drying Machinery 00., Louisville,

My invention relates to manifolds for driers of the type disclosed in Patent No. 1,139,663,0f May 18, 1915, and has reference more particularly to a fabricated unit as distinguished from a castiron one.

- increases.

The object of the invention is to provide a manifold which is suitable for pressures for which a, cast iron manifold is not suited,and also to provide passages which offer less resistance to now, both in cross-sectional area and wall texture.

Another object of the invention is to provide a manifold, the generic features of which are suitable for both high and low pressure driers.

With these and other objects in view, my inven tion consists in the combination of parts shown in the accompanying drawing and described in the specification, and more particularly pointed out in the claims.

In the appended drawing, Figure 1 is a fragmentary elevation of a manifold for high pressure, embodying my invention. A portion of same has been broken ofi to show the details of construction.

Figure 2 is a section on line 2-2, Figure 1, and

Figure 3 is an elevation of a bucket for a manifold to be used for low pressure.

Referring to thedrawing, the manifold comprises a dished member or section 5 and a disc member or section 6 located within the dished member but spaced from the bottom of same by stay bolts l0 which connect the two members together. The stay bolts provide the necessary clearance between the members 5 and 6 of the manifold to accommodate therebetween a plurality of scoops I spaced equi-angularly through the radial area in accordance with the number 7 of scoops used. As shown in the drawing, three such scoops are provided in this particular structure.

across the entire radial distance of the manifold, said wall extending or continuing into a retaining wall 9 from substantially the central part of the manifold, thetwo walls 8 and 9 diverging as their distance from the center of the manifold The retaining wall 9 stops short of the openings for the inner circle of the tubes.

Preferably, the walls 8 and 9 of the scoop are united by side walls ll, so that the scoop forms a unit that maybe introduced between the members 5 and 6 of the manifold.

At the juncture of the walls 8 and 5, anipple- I2 is provided in one of the side walls II to pass through the bottom of the dished member 5."

In addition, the two members 5 and 6 have.

Each scoop has a scooping wall 8 extending not connected with the inner space H formed by spacing the two members 5 and 6. These tubular members provide air for drying into the interior of the drier and also access in case of tube replacement. I

As shown in Figures 1 and 2, when the manifold revolves clockwise, the steam supplied through tubes fitting the openings I6 and I1 passes out into the manifold as condensate that accumulates in the bottom of any of the spaces l4 formed between the walls 8 of any of the adjacent scoops, and it is forced, due to the rotation, to travel with said wall until gravity moves the condensate toward the narrower end of the scoop. As the scooping Wall 8 approaches the vertical plane, the quantity of condensate converging toward the nipple increases, due to the convergency toward the nipple of the scooping and retaining walls 8 and 9. In consequence of that, the entrapped condensate is able to build up a hydrostatic head which facilitates the discharge of the condensate through the nipple l2.

As shown in Figures 1 and 2, the structure is designed for high pressure steam. For lower steam pressure driers the-distance between the mem bers 5 and 6 is materiallyincreased. The di-' same as shown in Figures 1 and 2, but in lieu of having parallel walls H, the walls II'- in which the nipple I2 is located is parallel withthe bottom of the dished member 5, but the wall 15 Oppo site the wall II, which is in proximity of the member 6 isconverging toward'the nipple from where it meets the retaining wall 9'. As will be seen from Figure 3, the scooping wall 8' extends similarly through the entire radial distance of the manifold unit.

From the above description, it will be-seen that the scooping units divide the space between the two members into angular chambers and the ac--v cumulation of condensation of each ofthe chambers is discharged through the scoop lying within that chamber. It is understood that the retaining wall of the scoop lies in the said chamber,

from which it discharges thecondensation.

vergency between the walls 8 and. 9 is retained, I
